MAROEITLUS M. HITT, OF LURAY, VIRGINIA, ASSIGNOR OF ONE-THIRD TO JOHN A. BROADDUS, OF SAME PLACE.

AUTOMATIC CUT OFF AND FILTER.

SPECIFICATION forming part of "Letters Patent No. 643,35 5, dated February 13, 1900.

Application filed April 15,1899. Serial No- '713,125 (No modelfl T ail whom it may 00771067 71 Be it known that I, MAROELLUS M. HITT, residing at Luray, in the county of Page and State of Virginia, have made certain new and useful Improvements in Automatic CutOffs and Filters, of which the following is a specification.

My invention is designed and adapted for use as an attachment of a rain spout or pipe which conducts water from a roof into a cistern or storage-tank. As is well known,when

rain falls the water which first comes off a roof carries along with it more or less dirt, trash, and organic and mineral matter, and is there: by rendered unfit for drinking, if not for other uses in domestic service. My invention is adapted to turn aside this foul or dirty water, and thus prevent its entering the cistern, after which it operates automaticallyto deliver the cleaner water to the latter, besides filtering it on its passage thereto.

The features constituting the improvement are hereinafter described and claimed.

In the accompanying drawings, two sheets, Figure 1 is a central Vertical section of the apparatus embodying my invention. Fig. 2 is a plan View of the same. Fig. 3 is a vertical section on the line3 3 of-Fig. 2. Fig. i is a perspective view illustrating the application of my invention as required for practical use. Fig. 5 is a side View of the apparatus, the cut-off and filter attachment being shown in the position required for conducting clean water to a cistern. Fig. 6 is an end View showing the parts in the same position as in Fig. 5.

A indicates the tank or receptacle for dirty water, 13 the automatic cut-off and filter constituting part of the spout or water-conductor leading to a cistern, and O the water-receptacle constituting a counterbalance for the pivoted cut-off.

D indicates the adjustable spout for gaging the delivery of water from the'tank A to the counterbalance O.

The aforesaid tank A is preferably constructed of galvanized iron, and is open at the top, which is inclined, as shown, and also cut out on the sides to allow overflow in case of necessity. The combined cut-ofi and filter attachment B is arranged and supported in the top of said tank A at an inclination of about thirty degrees. the down-spout 1, connected with the eavestrough, is attached to the conductor 2, (see Fig. 1,) which passes through the tank A to acistern. (Not shown.) The automatic cutoff B is interposed in this conductor 2,]and when in one position, Fig. 5, it forms practically a continuation of the same; but when As shown in Fig. 4,

tilted, as shown in Fig. 1, it operates as a cutoff proper and accordingly discharges water into the tank A. As shownin Fig.1, the cut-off section 3 is pivoted at t to a supporting-hanger 5, which is permanently and rigidly attached to the enlarged sections 6 of the T conductor 2. The cut-off section 3 is practically a short open trough having the same radius as the fixed sections 6 before referred to. One end of said cut-01f section is weighted at 7, and its opposite end is provided with a filter 8. The latter is formed of sponge or other-material permeable for water and arranged between two reticulated partitions 9. By this construction the filtering substance may be readily removed when required for the purpose of cleansing it. In its normal po* sition the cut-off section 3 is tilted, as shown in Fig. 1, and consequently water delivered to it will be discharged into the tank A. On the other hand, when in practical alinement with the conduct-or 2, as shown in Fig. 5, it

ceases to discharge water into tank A, and the same passes onward, through the filter S, into the section of the delivery-pipe which extends to the cistern. The meansfor thus shifting or tilting the cutoff section 3 is the water-counterbalance C, before referred to. The same is a small, oblong, box-like waterreceptacle, which is open at the top and pivotally connected with the lower-end of the cut-0E section 3 by means of a bent rod 10. It will now be perceived that when the first wash of a roof is delivered into the tank. A, as indicated by arrows, Fig. 1, and fills the same .up to the lateral discharge-spout B, it may flow through the slot'or opening 11 (see Fig. 2) in said spout, and thereby be delivered into and fill the counterbalance O. The lat- ICO ' so long as it remains filled with water, and

consequently the clean water following the first wash, which has thus been delivered into tank A, will be filtered and conveyed to the cistern. It is further obvious that this position and operation will be maintained so long as the rain continues.

In order to provide for discharge of water from the counterbalance O, and thereby permit restoration of the cut-off section 3 to its original posit-ion, Fig. 1, I provide the same with an orifice 12, (see Fig. 3,) which permits the water therein to leak out in a comparatively short time. I also provide for a similar-discharge of the contents of tank A by setting the plug 13 of cock 1 L (see Fig. 2) in such position as allows a slow escape of water. Thus in a short time afterthe fall of rain has ceased the entire apparatus will be again in condition to operate as before and to avert 'from the cistern the first wash of the roof.

' The lateral discharge-spout D, before referred to, consists of two partsa fixed section 15 and a movable section 16, which isadapted to slide upon the former. The section 16 has a longitudinal slot 11, and it is 3 to tilt back obvious that by longitudinal adjustment of said section 16 more or less of said slot will be exposed, as shown in Fig. 2. By this means the quantity of water which may pass through the slot 11 in a given time is easily regulated. It is further apparent that if the overflow from tank A is in excess of the quantity which can pass through the slot 11 it will be dischargedlaterallyupon theground. Asshown in Figs. 1 and 2, a small slot or opening 17 is formed in the bottom of cut-off section 3 for the purpose of allowing sufficient water to discharge from said section into the tank A to supply the waste which necessarily goes on from the tank itself and from the counterbalance 0 during the time water is being discharged into the cistern. In other words, the leak or discharge through said slot 17 prevents the counterbalance O becoming lightened sufficiently to allow the cut-off section prematurely to its normal position, Fig. 1.

Myiin pro ved apparatus thus constitutes an efficient automatic cut-off for foul or dirty water and an equally efficient filter for the comparatively clean water following the first wash of the roof, and it automatically discharges and read j usts itself after every operation.

It will be seen that the cut-off section 3 being open at the top the removal of bugs and other organic or mineral matter, which may collect adjacent to the inner filter-partition 9, may be effected without difficulty.

The entire cut-off and filter attachment B, together with the conductor-sections 2 forming the ends thereof, may be quickly attached to or removed from the tank'A. Each of the said sections 2 rests in a cut-out portion of the tank and is secured in such position by means of a drop-pin 18 and ahinged bail 19.

(See Figs. 1 and 6.) The said bail consists of a stout wire or small rod which is hinged or pivoted to the tank on one side of the conductor-section 2 and is adapted to be hooked into the tank on the opposite side, passing intermediately over the conductor 2, as shown in Fig. 6. When the cut-off and filter attachment B is detached from the tank, it may be placed in .the latter for the purpose ofprotection and economy of space in storage or transportation.

hat I claim is 1. In an automatic cut-oif and filter-apparatus, the combination, with the tank, having its top inclined and cut out at the upper and lower sides, of the cutoff and filter attachment, which fits and is held in such cut-out portions, as shown and described.

2. The combination, with a tank, of a cutoff and filter attachment which is fitted in the top' of said tank'and supported thereby, and a hinge-bail and drop-pin for securing said attachment removably, as shown and described. i

3. Thecombination, with a water receptaole or tank, of a cut-off and filter attachment including as part of the same, a filter-compartment, arranged at one end of said section, and consisting of reticulated partitions and filtering material placed in the space between them, substantially as shownand described.

4:. The combination, with the water tank or receptacle, and a pivoted cut-off arranged upon the same, of a lateral discharge-spoutforming an attachment of said tank, and composed of a fixed section and a movable section having a lengthwise slot which is exposed more or less according to the adj ustment of the movable section, and a watercounterbalance arranged to receive the'water discharged though said slot, substantially as shown and described.

5. The combination, with a water-tank, or receptacle for the first wash of a roof, the same having a lateral discharge-pipe, of an automatic cut-off and filter attachment comprising alined, fixed, and inclined conductors 2, the intermediate, pivoted filter-section B,

having a discharge-slot in the bottom thereof, a water-receptacle hung from the filtersection, and constituting a counterbalance for the same, and having a dischargeslot in the bottom, as shown and described.
